+# Note [slotting support]
+# -----------------------
+# Gentoo's layout for binutils files is non-standard as Gentoo
+# supports slotted installation for binutils. But many tools
+# still expect binutils to reside in known locations.
+# binutils-config package restores symlinks into known locations,
+# like:
+# /usr/bin/${CTARGET}-<tool>
+# /usr/bin/${CHOST}/${CTARGET}/lib/ldscrips
+# /usr/include/
+#
+# Note [tooldir hack for ldscripts]
+# ---------------------------------
+# Build system does not ./configure to tweak evey location we need
+# for slotting binutils. This note is about SCRIPTDIR define.
+#
+# SCRIPDIR defines 'ldscripts/' directory location. SCRIPDIR value
+# is set at build-time in ld/Makefile.am as: 'scriptdir = $(tooldir)/lib'
+# and hardcoded as -DSCRIPTDIR='"$(scriptdir)"' at compile time.
+# Thus we can't just move files around after compilation finished.
+#
+# Our goal is the following:
+# - at build-time set scriptdir to point to symlinked location:
+# ${TOOLPATH}: /usr/${CHOST} (or /usr/${CHOST}/${CTARGET} for cross-case)
+# - at install-time set scriptdir to point to slotted location:
+# ${LIBPATH}: /usr/$(get_libdir)/binutils/${CTARGET}/${BVER}
